Factor the expression below.
9x^2 - 1

x=1/3

Step-by-step explanation:

9x^2-1=0

Add 1 to both sides

9x^2=1

Divide both sides by 9

x^2=1/9

Square root both sides

x=1/3

   or    

Step-by-step explanation:

   or    

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

1. minimum

2. 6400

3. eight

hope this !
